Simmod SIM-EF-E-PLOCK Overview

The EF Lens to Sony E Body Positive-Lock Adapter from Simmod enables you to mount a Canon EF-mount lens onto a Sony E-mount camera. The aluminum adapter features a solid stainless steel positive-locking ring and features a support foot with 1/4"-20 and 3/8"-16 mounting threads.

For Professional Cinema Use
The high-grade aluminum construction and PL-style positive-locking collar provide a secure lock, evenly distributing torque and preventing lens twist during follow-focus pulls, gimbal work, or heavy cine-rig setups.
Zero Play
Unlike friction-based adapters, the positive-locking system clamps the EF lens in place for a cinema-ready mount interface with no shift or rattle.
Optimized for Sony E-Mount
Compatible with Sony E-mount cameras, this adapter preserves optical performance with a precision-machined flange distance that guarantees accurate infinity focus.

The internal surface features a matte-black, anti-reflection coating to reduce stray light and enhance contrast.

Asked by: Oliver
The Simmod EF Lens to Sony E Body Positive Lock Adapter is a fully mechanical adapter with no electronic contacts, so it does not support electronic aperture control or communication with Canon EF lenses on Sony cameras.
